The required serialization of NOSY_IOC_START and NOSY_IOC_STOP is
already provided by the client_list_lock.
NOSY_IOC_FILTER does not really require serialization since accesses
to tcode_mask are atomic on any sane CPU architecture. Nevertheless,
make it explicit that we want this to be atomic by means of
client_list_lock (which also surrounds the other tcode_mask access in
the IRQ handler). While we are at it, change the type of tcode_mask to
u32 for consistency with the user API.
NOSY_IOC_GET_STATS does not require serialization against itself. But
there is a bug here regarding concurrent updates of the two counters
by the IRQ handler. Fix it by taking the client_list_lock in this ioctl
too.

Extend copyright note to 2007, c.f. Kristian's git log.
Includes:
- replace some <asm/*.h> by <linux/*.h>
- add required indirectly included <linux/spinlock.h>
- order alphabetically
Coding style related changes:
- change to utf8
- normalize whitespace
- normalize comment style
- remove usages of __FUNCTION__
- remove an unnecessary cast from void *
Const and static declarations:
- driver_name is not const in pci_driver.name, drop const qualifier
- driver_name can be taken from KBUILD_MODNAME
- the global variable minors[] can and should be static
- constify struct file_operations instance
Data types:
- Remove unused struct member struct packet.code. struct packet is
only used for driver-internal bookkeeping; it does not appear on the
wire or in DMA programs or the userspace ABI. Hence the unused
member .code can be removed without worries.
Preprocessor macros:
- unroll a preprocessor macro that containd a return
- use list_for_each_entry
Printk:
- add missing terminating \n in some format strings

This adds the traffic sniffer driver for Texas Instruments PCILynx/
PCILynx2 based cards. The use cases for nosy are analysis of
nonstandard protocols and as an aid in development of drivers,
applications, or firmwares.
Author of the driver is Kristian Høgsberg. Known contributers are
Jody McIntyre and Jonathan Woithe.
Nosy programs PCILynx chips to operate in promiscuous mode, which is a
feature that is not found in OHCI-1394 controllers. Hence, only special
hardware as mentioned in the Kconfig help text is suitable for nosy.
This is only the kernelspace part of nosy. There is a userspace
interface to it, called nosy-dump, proposed to be added into the tools/
subdirectory of the kernel sources in a subsequent change. Kernelspace
and userspave component of nosy communicate via a 'misc' character
device file called /dev/nosy with a simple ioctl() and read() based
protocol, as described by nosy-user.h.
The files added here are taken from
git://anongit.freedesktop.org/~krh/nosy commit ee29be97 (2009-11-10)
with the following changes by Stefan Richter:
- Kconfig and Makefile hunks are written from scratch.
- Commented out version printk in nosy.c.
- Included missing <linux/sched.h>, reported by Stephen Rothwell.
"git shortlog nosy{-user.h,.c,.h}" from nosy's git repository:
Jonathan Woithe (2):
Nosy updates for recent kernels
Fix uninitialised memory (needed for 2.6.31 kernel)
Kristian Høgsberg (5):
Pull over nosy from mercurial repo.
Use a misc device instead.
Add simple AV/C decoder.
Don't break down on big payloads.
Set parent device for misc device.
As a low-level IEEE 1394 driver, its files are placed into
drivers/firewire/ although nosy is not part of the firewire driver
stack.
I am aware of the following literature from Texas Instruments about
PCILynx programming:

Add a xen_emul_unplug command line option to the kernel to unplug
xen emulated disks and nics.
Set the default value of xen_emul_unplug depending on whether or
not the Xen PV frontends and the Xen platform PCI driver have
been compiled for this kernel (modules or built-in are both OK).
The user can specify xen_emul_unplug=ignore to enable PV drivers on HVM
even if the host platform doesn't support unplug.

Use xen_vcpuop_clockevent instead of hpet and APIC timers as main
clockevent device on all vcpus, use the xen wallclock time as wallclock
instead of rtc and use xen_clocksource as clocksource.
The pv clock algorithm needs to work correctly for the xen_clocksource
and xen wallclock to be usable, only modern Xen versions offer a
reliable pv clock in HVM guests (XENFEAT_hvm_safe_pvclock).
Using the hpet as clocksource means a VMEXIT every time we read/write to
the hpet mmio addresses, pvclock give us a better rating without
VMEXITs. Same goes for the xen wallclock and xen_vcpuop_clockevent

This patch removes the code which disables 100Mbps advertising when

At higher speed it's good to be nice to the internal state machine

The _ADR object is used to provide OSPM with the address of one device on its
parent bus. In course of finding ACPI handle for the corresponding PCI device,
we will firstly evaluate the _ADR object and then compare the two addresses to
see whether it is the target ACPI device. But for one PCI device(0000:00:00.0)
under the PCI root bridge, the corresponding address will be constructed as
zero.In such case maybe the ACPI device without _ADR object will be misdetected
and then be used to create the relationship between PCI device and ACPI device.
